NEW YORK (MarketWatch) -- The dollar briefly extended gains and Treasury prices slipped on Friday after the U.S. Labor Department said the economy added 115,000 jobs in April, fewer than economists expected. The number of jobs added in March and February were revised up and the unemployment rate fell to 8.1% as people dropped out of the labor force. The euro spiked down to $1.3110 before recovering to $1.3139, little changed from before the data and down from $1.3151 Thursday. The dollar index , which measures the greenback against a basket of six major currencies, stood at 79.236, from 79.213 in late North American trading Thursday. Yields on 10-year notes , which move inversely to prices, turned up 1 basis point to 1.95%.
